A PIN only protects you if it is hard to guess, and the PINs people invent for themselves are notoriously easy to guess. This generator picks each digit at random and then throws out the patterns attackers try first, so you get a code with no connection to your birthday, your address or the shape of a keypad.
How to use the PIN generator
- Choose a PIN length from 3 to 12 digits. Bank cards usually use 4; phones often allow 6 or more.
- Enter how many PINs you want, up to 200 in one batch. No PIN repeats within a batch.
- Keep Avoid easy-to-guess PINs ticked unless you need a purely uniform draw.
- Press Generate and copy the PIN you want to use.
The tape shows how many PINs of that length exist, how many were filtered as weak and the odds that a single random guess hits yours.
How strong is a random PIN?
Every digit has ten possibilities, so a PIN of length n has
| Length | Possible PINs | Weak patterns removed | One-guess odds |
|---|---|---|---|
| 4 digits | 10,000 | 203 | 1 in 9,797 |
| 5 digits | 100,000 | 112 | 1 in 99,888 |
| 6 digits | 1,000,000 | 1,100 | 1 in 998,900 |
| 8 digits | 100,000,000 | 106 | 1 in 99,999,894 |
What makes PINs safe in practice is the lockout: most cards and phones block further attempts after a few wrong tries. With three tries against a random 4-digit PIN from this tool, an attacker’s chance is 3 ÷ 9,797, about 0.03%.
Which patterns are filtered?
With the filter on, the generator rejects any PIN that is:
- All one digit: 0000, 7777, 999999.
- A straight run up or down: 1234, 3456, 9876, 012345.
- A repeated pair: 1212, 9090, 454545.
- A year (4-digit PINs): 1950 through 2039, the range of most birth, wedding and graduation years.
- A repeated triple (6-digit PINs): 123123, 007007, 911911.
These are exactly the guesses an attacker tries first. Published analyses of leaked PIN lists have found that 1234 alone accounts for roughly one PIN in ten, and a handful of the patterns above cover a large share of the rest. U.S. digital identity guidelines from NIST likewise recommend rejecting commonly used and predictable secrets.
Worked example: a new debit card PIN
You need a 4-digit PIN for a new card.
- Length 4, how many 5, filter on. Suppose the tool returns 8473, 2958, 6017, 5340 and 9182.
- None of them is a year, a run or a repeated pattern, and each was chosen from 9,797 equally likely options.
- Pick one, practice it a few times, and do not write it on the card or store it next to the card.
If you use one PIN across several cards, a single leak exposes them all — generating a separate PIN for each costs nothing.
Tips for living with a random PIN
- Memorize by chunks: read 8473 as “eighty-four, seventy-three” rather than four separate digits.
- Don’t reuse old PINs or derive new ones from them (8473 → 8474).
- Shield the keypad when you type; cameras and onlookers defeat any PIN.
- Use longer PINs when allowed: six digits multiply the possibilities by 100.
For codes that mix letters and digits, try the number and letter set generator. For online accounts, a long password from the password generator is far stronger than any PIN.

Frequently asked questions
What makes a PIN weak?
Patterns people choose on purpose: repeated digits (1111), runs (1234, 9876), repeated pairs (1212) and birth or anniversary years (1985). Attackers try those first, so a short list of guesses covers a large share of real PINs.
How many 4-digit PINs are there?
There are 10,000, from 0000 to 9999. This tool's weak-pattern filter removes 203 of them, leaving 9,797 that it can choose from.
Is a 6-digit PIN much safer than a 4-digit PIN?
It has 100 times as many possibilities: 1,000,000 instead of 10,000. If a device locks after a few wrong tries, a random 6-digit PIN is very hard to guess.
Are the PINs stored or sent anywhere?
No. They are created by your browser's cryptographic random generator and exist only on your screen. Clear or close the page when you are done.
Can a PIN start with zero?
Yes. Zero is as likely as any other digit in every position, so a PIN like 0472 is perfectly valid. Most cards and phones accept a leading zero.
